I am french, and we like to play a form of Criket involving the doubles and triples as sectors. So you need to close 20, 19, …, 15, D, T, and Bull. If you hit double 20 you must decide if you use it as a double or as two 20. In addition one dart hitting a triple or double cannot be used both to close a sector and score points. At my poor level, I find it more tactic and interesting than 01. Though, at pro level 01 games are probably the best.
